Specification of Letters Patent.

Patented Feb. 13, 1917.

Application filed May 18, 1916. Serial No. 98,327.

To all whom it may concern Be it known that I, WILLIAM C. PARSONS, a citizen of the United States, residing at Cuyahoga and State of 'Ohio, have invented certain new and useful Improvements in VVater-I-Ieaters, of which the following is a specification.

This invention relates to water heaters of thattype in which the water is caused to flow through'a plurality of superposed sections confined in a casing, with a burner below, the sections being of that type having a central water connection therebetween, and curved passages communicating at opposite ends with said connection, through which passages the water flows in its course upwardly through the sections, the heater being the kind commonly employed for domestic purposes, although capable of other uses.

The object of the invention is to provide an improved heating element characterized by the novel construction of the water passages in order to produce a free and uninterrupted flow of water, and efficient heatmg spaces.

In the accompanying drawings,

Figure 1 is a side elevation of the heater, the casing being partly broken away.

Fig. 2 is a plan of one of the heating elements.

Fig. 3 is a section on the line Fig. 2.

Referring specifically to the drawings, 6 indicates the heater casing, 7 the burner at the bottom and 8 the top or cover. Within this casing are a series of superposed sections. Each section has a central hub part 9 with a partition 10 extending diagonally across the same and dividing it into inlet and outlet passages. These sections are connected together by short pipe connections 11 screwed into the opposite ends of the hub.

A pair of segmental water tubes or passages 12 are located at opposite sides of each section, and these are connected at their opposite ends to inwardly curved branch pipes or passages 13 which unite into single Copies of this patent may be obtained forfive passages 14 which open into the hub or central part, these branch pipes 13 forming flue spaces 16 therebetween. One pipe let opens above the partition 10 and the other below the same, whereby the water circulates from the lower central inlet to the hub out through one pair of passages 13 and thence around through the passages 12 to the other pair of passages 13 and thence back to the outlet of the hub.

By extending the branches 13 in opposite curved directions to the passages 12 the eddies produced by sharp angles at the junction of straight and curved passages are avoided, and the spaces between the branches 13 permit the flow of the products of combustion therebetween, and in arranging the sections they will be staggered, that is, the segmental passages 12 of one section will be located above the spaces between the branches 13 of the section below. In this way, the parts 1a will lap the openings 15 in the sections, and the segments 12 will lap the spaces 16 referred to, so that tortuous passages for the products of combustion are provided, and the full effect of the heat is obtained. The casing fits rather closely around the sections, so that the heat is confined to the latter. The cooler water in its course enters the lower section and flows upwardly through the others in an obvious manner.

lVhat I claim as new is:

A water heater section comprising a central hub having a partition across the same, pipes 14: extending oppositely from said hub and connected thereto respectively above and below the partition, segmental pipes 12 at the rim, and a pair of branch pipes 13 connecting each of the pipes 14: and the 0pposite ends of each of the segmental pipes, said ends and the branch pipes being spaced apart to form outer fines for heat.

In testimony whereof, I do affix my sig nature in presence of two witnesses.

WILLIAM C. PARSONS.
